IMPROVBD MACHINE POR STAMIING AND SHAPING LEATHER.

TO ALL WIIOM IT MAY' CONCERN: I

Be it known that I, BENJAMIN B. HARRIS, of Lockport, in the county of Will, and State of Illinois, have invented a new and improved Device for Stamping and Shaping Leather; and I do hereby declare thatthe following is a full, clear, and exact description thereof, which will enable others 'skilled in the art to make and use the saine, reference being had to the accompanying drawings, forming part of this specifi-cation.

This invention relates to an improved device for stamping and shaping leather, and consist in a combination of toggle-joint, levers, springs, follower, dies and knife, as hereinafter more fully described. In the accompanying drawings- Figure l isl a. side elevation, and

Figure 2 a front elevation of my improved machine.

Figure 3 is a top view ct' a die and knife, and

Figure 4 is a section thereof on line x :u of fig. 3.

Simiiar letters of reference indicate like parts.

A A is the frame, in which the parts of the machine are disposed. ,The post B plays through the loose mortise a in A, and is hinged at e to the follower C, which is pivoted to the frame A at c', forming with it a togglejoint, the spring U keeping the `joint open. The lever of the second order, D, having its fulcrum at S, and connected by the elbow or bell-crank E, stirrup e, and hookf, to the post B, operates the toggle-joint and brings the follower C down upon the knife lc, carried in the knife or die-plate I. Gr is the stage, borne on the post B, having the dove-tailed groove g to receive the die or knife-plate I, and a hole, m, for the-leather when cut to fall through. Dove-tailed pin L holds the die-plate I in place.

What I claim as new, and desire to secure by Letters Patent, is-

frame A, having the stage-post B hung from it, and playing through e. loose mortise, in manner substantially as herein shown and described. I

2. rEhe die or knife-plate I, carrying the knife 7c, sliding in the dove-tailed groove g, on stage G, ivliichis furnished with the hole m, and bolted by the dove-tailed pin L to the stage G, all as set forth, in combination with the toggle-joint, levers, and followers, substantially as herein shown and described.
